He's not completely wrong; getting dep ordering with missing intermediaries isn't trivial. If upstream takes upto 50 days from release to drop a srpm, we need to consider implications in both directions right ? and at that point ( it has happened ) we might be looking at rebuilds from 50+X days. Where X might even be 20 - 45 days itself. in 5.3's release time we had to traceback to a fastrack built package from 5.1's days. - KB
